Book Information and Supplemental Files
1. The text
Foundations
of Linear and Generalized Linear Models, published by Wiley in
February 2015, presents an overview of the most commonly used
statistical models by discussing the theory underlying the models and
showing examples using R software. The book begins with the
fundamentals of linear models, such as showing how least squares
projects the data onto a model vector subspace and orthogonal
decompositions of the data yield comparisons of models. The book then
covers the theory of generalized linear models, with chapters on
binomial and multinomial logistic regression for categorical data and
Poisson and negative binomial loglinear models for count data. The
book also introduces quasilikelihood methods (such as generalized
estimating equations), linear mixed models and generalized linear
mixed models with random effects for clustered correlated data,
Bayesian linear and generalized linear modeling, and regularization
methods for highdimensional data. The book has more than 400
exercises. The book's
website
contains supplementary information, including data sets and corrections. Here is
an interview
about the book in the Wiley publication "Statistics Views."
2. The
book
Strength in Numbers: The Rising of Academic Statistics Departments in
the U.S., coedited with XiaoLi Meng, has been published by
Springer (2012). This book has a chapter for each of about 40
Statistics and Biostatistics departments founded in the U.S. by the
mid1960s, describing the evolution of those departments and the
faculty and students who worked in them. Included are about 200
historical photos. See
the Springer site for other details.
3. The
text
Categorical Data Analysis, 3rd Edition
has been published
in its third edition (Wiley, 2013). I've constructed
a Website for
Categorical Data Analysis that provides datasets used for
examples, solutions to some exercises, information about using R, SAS,
Stata, and SPSS software for conducting the analyses in the text, and
a list of some typos and errors.
Here is
an interview
that the Wiley publication "Statistics Views" conducted with me to
mark the publication of the new
edition. A website
for second edition has some material for the 2nd edition.
Dr. Laura Thompson has prepared a detailed manual on the use of R or
SPlus to conduct all the analyses in the 2nd edition. Here is a
copy of this excellent resource:
Laura
Thompson R and S manual for CDA.
4. The
text
Analysis of Ordinal Categorical Data
(Wiley, 1984) has
been revised, and the second edition was published in 2010.
My ordinal categorical
website contains (1) data sets for some examples in the
form of SAS programs for conducting the analyses, (2) examples of the
use or R for fitting various ordinal models, (3) examples of the use
of Joe Lang's mph.fit R function for various analyses in the book that
are not easily conducted with SAS, Stata, SPSS, and standard functions
in R, and (4) corrections of errors in early printings of the book
(Please send me any that you notice).
5. The
text
Statistics: The Art and Science of Learning from
Data (4th edition, Pearson, 2017) was written with Christine
Franklin of the University of Georgia. The latest (4th) edition was
coauthored by Bernhard Klingenberg of Williams College, who has
developed a wonderful set of applets and other resources for teaching
from the book
(see Art of Stat ). This text is
designed for a oneterm or twoterm undergraduate course or a high
school AP course on an introduction to statistics, presented with a
conceptual approach. The link
AFK
has a Table of Contents and information about the book. Many
supplemental materials are available from Pearson, including an
annotated instructor's edition, a lab workbook, videotaped lectures,
and software supplements. Contact Ms. Suzanna Bainbridge, the
Acquisitions Editor for Statistics at Pearson Education, for details
(suzanna.bainbridge@Pearson.com). An Italian translation of the 3rd
edition is now available, thanks to Giuseppe Espa, Rocco Micciolo,
Diego Giuliani and Maria Michela Dickson at the Univ. of
Trento.
6. The
book
Statistical Methods for the Social Sciences, (5th edition,
Pearson, published January 2017; 4th edition, by Agresti and Finlay,
published 2009) is designed for a twosemester sequence. The book
begins with the basics of statistical description and inference, and
the second half concentrates on regression methods, including multiple
regression, ANOVA and repeated measures ANOVA, analysis of covariance,
logistic regression, and generalized linear models. The new edition
adds R and Stata for software examples as well as introductions to new
methodology such as multiple imputation for missing data, random
effects modeling including multilevel models, robust regression, and
the Bayesian approach to statistical inference. For applets used in
some examples and exercises of the new edition, go
to applets.
These were designed by Bernhard Klingenberg for the text "Statistics:
The Art and Science of Learning from Data" by Agresti, Franklin, and
Klingenberg. For most of the data sets from the text, click
on data for
SMSS. (Thanks to Margaret Ross Tolbert for the cover art,
based on northcentral Florida springs.) Jeffrey Arnold of Emory
University kindly set up a R package at CRAN for R users to be able to
access the datasets used in the 4th edition of this text. See
R
data files. For examples of the use of the software Stata
for various analyses for examples in the 4th edition of this text, see
the useful site set up by
the UCLA
Statistical Computing Center. I am also pleased to report (due to my
partial Italian heritage) that there is also an Italian version of the
first ten chapters of the 4th edition of this book (Statistica per
le Scienze Sociali) and of the entire book (Metodi Statistici
di Base e Avanzati per le scienze sociali) published by Pearson,
and there is also a Portuguese version  see "Metodos Estatisticos
para as Ciencas Socias" at
Portuguese SMSS
 and a Chinese version, and it is being translated into Spanish.
I have developed Powerpoint files for lectures from Chapters 112 of
this text that are available to instructors using this text.
(Chapters 17 of these have also been translated into Spanish by Norma
Leyva of Universidad Iberoamericana in Mexico.) Please contact me for
details. Finally, here is a link to a workshop held by the Department of
Sociology, Oxford University, in 2012 that
discussed issues
in the teaching of quantitative methods to social science
students.
7. The text
An Introduction to Categorical Data Analysis
is in its 2nd edition (Wiley, 2007), with a 3rd edition planned for
2018 that will incorporate R software material. (Suggestions for this
revision are welcome!) This book, which presents a nontechnical
introduction to topics such as logistic regression, is a
lowertechnicallevel and shorter version of the "Categorical Data
Analysis" text mentioned above. I've constructed a website for these
texts that provides information about the use of
Software for
Categorical Data Analysis such as SAS, R and SPlus, SPSS,
Stata, and StatXact. For SAS files containing data sets from the
text, click on Data sets for
Intro CDA. There are some very good online notes, using
R code, developed by instructors who have used this text. For
example, see the website
of Brett
Presnell for a course on this topic at the University of Florida.
Brett has improved some of my own course notes and added R code and
output. Here are
some corrections
for the 1st edition of this book and a pdf file
of corrections for the 2nd
edition.
Short Courses
I have taught short courses on categorical data analysis topics for
many universities, professional organizations, conferences, and
companies, mainly in Europe and the U.S. These range in length
from halfday to a week, most commonly one or two days on topics
such as "Modeling Ordinal Categorical Responses," "Analyzing
Clustered Categorical Data," "Introduction to Categorical
Data Analysis," "Discrete Data Analysis," and "Generalized
Linear Modeling."

Here is a seminar (in mp4 format) on the
Jacki and Alan's

Poundwise guide to London from the DecemberJanuary 2007
issue of Gainesville magazine. (My wife Jacki Levine is founder
and editor of this bimonthly magazine.)

My home page picture at the top was taken by Jacki Levine in the
Forest of Dean, among the May bluebells. It is an old picture, but
below is a more recent one, taken while I was teaching a short course
at the International Workshop on Statistical Modelling, in Linz,
Austria in July 2015. This is a very friendly conference, typically
held in some of the nicest European cities and thus a good way to get
to know European statisticians. See
IWSM. The
Statistical Modelling Society also sponsors a
journal, Statistical
Modelling.
